1.3- Collision Theory

the values of x and y are called…

reactant orders

Collision theory states that reaction rates depend upon:

the number of collisions per unit of time and the fraction of these collisions that succeed in producing products.

if the rate of collisions per second were equal to the rate of reaction…

every reaction would be extremely rapid

what is the activation energy?

The minimum kinetic energy that the reacting species must have in order to react

what is a reaction mechanism?

the series of steps in which a reaction occur

what’s the only thing that can change the activation energy of a reaction?

change its reaction mechanism

collision possessing the activation energy don’t always…

result in a reaction

in addition to attaining activation energy, the _____ and _____ of reacting particles must also be favourable for a successful collision to occur

geometric shape, and the collision geometry

increased ____, _____, and ____ all increase the frequency of collisions leading to an increase in reaction rate.

temperature, concentration and surface area

the presence of a ____ and ____ both increase the fraction of collision that are successful

catalyst, and increased temperature
